I don't exactly have any wise advice to give other than live the time you have left to the fullest and spend time with your gf, friend and family. (Adding a ? Here or reddit won't let me post)

I can recommend a movie that might help you see your situation in a different perspective - Me and Earl and the Dying Girl.

It's not completely sad, wouldn't have mentioned it otherwise :P. It's mostly a comedic movie with the death part being obviously sad but it also ends on a positive hopeful note. That's actually why I recommended it, for the hopeful ending to make your own situation feel slightly better.
I totally get if you don't wanna watch anything that reminds you of your situation though, no worries. Wish you the best for what time you have left.
